Description


Updated samba packages that fix three security issues are now available for
Red Hat Enterprise Linux 7.

The Red Hat Security Response Team has rated this update as having Moderate
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.

Samba is an open-source implementation of the Server Message Block (SMB) or
Common Internet File System (CIFS) protocol, which allows PC-compatible
machines to share files, printers, and other information.

A denial of service flaw was found in the way the sys_recvfile() function
of nmbd, the NetBIOS message block daemon, processed non-blocking sockets.
An attacker could send a specially crafted packet that, when processed,
would cause nmbd to enter an infinite loop and consume an excessive amount
of CPU time. (CVE-2014-0244)

A flaw was found in the way Samba created responses for certain
authenticated client requests when a shadow-copy VFS module was enabled.
An attacker able to send an authenticated request could use this flaw to
disclose limited portions of memory per each request. (CVE-2014-0178)

It was discovered that smbd, the Samba file server daemon, did not properly
handle certain files that were stored on the disk and used a valid Unicode
character in the file name. An attacker able to send an authenticated
non-Unicode request that attempted to read such a file could cause smbd to
crash. (CVE-2014-3493)

Red Hat would like to thank Daniel Berteaud of FIREWALL-SERVICES SARL for
reporting CVE-2014-0244, and the Samba project for reporting CVE-2014-0178
and CVE-2014-3493. The Samba project acknowledges Christof Schmitt as the
original reporter of CVE-2014-0178, and Simon Arlott as the original
reporter of CVE-2014-3493.

All Samba users are advised to upgrade to these updated packages, which
contain backported patches to correct these issues. After installing this
update, the smb service will be restarted automatically.
